HOUSEHOLD-TOOL.

Tooll 'whom it may concern:

' Be it known that I, Join: C. Fons'ma, of

1 the reverse, movement of the handle. in

V 'Pittsbur ,in the vcounty of Allegheny and State of enns'ylvania, haveinvented certain 5 new and useful Improvements in Household- Tools, ofwhich the following is a specification. e

The invention provides a wrench for jar caps .of novel constructionwhich is adapted :for use interchangeably in tightening and looseningthe caps, with means holding the cap-embracing member normally open andre dy to beapplied'to a cap, said member a so serving as a ring forhanging the tool on a nailOr hook when not in use.

In the accompanying drawings, Figure 1 is a view in top plan of theimproved tool, the wrenchbeing in normal position for embracing a jarcap. -Fi 2 is a section of the xtool on line 22 of F 1. Fig. 3 is a toits outer edge flanged downwardly at 3 to grip the cap A. The band ispreferably provided with flat top portions 4 which are of decreasingwidth toward the center of the v band where it is relatively narrow, asindicated at 4'. This formation provides a gripping device of desirableresihenc without impairing its strength, and the at top portions providesurfaces for the handle connections.

A In the present ada. tation one extremity of handle 5 is flattene asshown and adjacent one edge is secured to one end of member 2 y ivot 6.F ed in the handle extremity is t e U-shaped s ot 7, the o positeextremi- "ties 7 7" of which are equa distances from pivot 6 and nearerthereto than the other portions of the slot, the latter being thuseccentric to pivot 6. Entered in the slot is pin 8 carried by the otherextremity of member2. I

' The U-sha ed slot, in conjunction with pin 8, pro 'des a double camconnection, member 2 beingcontracted on the ca for unscrewing the samewhen the ban e is spammin 01 Letters Patent. Application filed December18, 1909. Serial No. 588,414.

turned as in full lines of Fig. 3 with 'lot extremity 7 extended towarpin 8, while dotted lines in Fig. 3, contracts the pin for tighteningthe, cap, it being understood that by either use the requisite pressurefor loosening or tightening the cap is applied to the handle in thedirection in which the handle is moved for clamping member 2 thereon.The curvature of the slot proviches a cam connection which is much moreeffective and more nearly devoid of friction on pin 8 than is possiblewith a slot having straight lines.

The tongue-like rejection 9 tformed b theslot is provide at itsextremit' wit, a depression 9' which is I engaged y pin 8, as in Fig. 1,and holdsthe contracted member 2 normally expanded ready to embrace thecap andwith the handle projecting straight out. Thus the device isalways in position to be applied without making it necessary tomanipulate it tab both hands rior to placing it on the cap, and theringike member 2 ma: be convenientl used for hanging the too on a nailor hoo when not in service. 1

The tool handle is preferably formed of a' piece of plate-like byturning the longit dinal ed es upwardly as indicated at 0. The han 1c isslotted longitudinally at 11, and slidable on the top surface thereofbetween edges 10 is 4 the plate-like carrier 12, from which acan-cutting knife 13 projects through slot 11 as vi shown. The carrieris slidab y held on the handle by rivet 14 with head 14 at the underside of the handle adapted to bear on .the can top B,/as in Fig. 5, thusholding the handle properly spaced therefrom and forming a runner-likemember which facilitates eta], and is reinforced rojection 16 extendingm 1 6, in such use the handle bein reverse from the position shown inFig. 5

and serving as a lever for the cap removing jacent each other, saidmemberhavin a top portion which bears on the top suriace ofthe cap withsaidtop portion flanged downwardly to grip the side face of thecap,

' the end portions of said member being inflexible and its intermediateportion resilient, a handle pivoted to one end of the member, and acam-slot and pm connection between the handle and the other end of themember.

2. The combination of a cap-embracing band of resilient contractilematerial, the band ,beingrcurved in ring-like form with the. endsthereof adjacent each other, a

' handle pivoted to one end of the band, a'

3. The combination of a cap-embracing member shaped from a single pieceof metal with its ends adjacent each other, said member having flat topportions decreasing in width backwardly from said ends and also formedwith a depending cap engaging flange, a handle pivoted to the fiatsurface at one end of said member, and.a pin and slot connection betweenthe handle and the fiat top surface of the other end of said member. 1

4. The combination of a. cap-embracing member formed of resilientcontractile material and of ring-like form with its ends adjacent eachother, a handle pivoted to one end of the member, the handle formed witha double cam-slot, both ends of the slot being nearer the handle pivotthan the other portions of the slot the slot forming a tongue-likeprojection, the end of said projectlon being formed with a seat, and apin carried by the other end of said member and entered in the slot andadapted to be 45 engiaged by said seatfor setting said capem raclngmember in an expan ed inoperative position.

5. The combination of a cap-embracing member shaped from a single ieceof metal with its endsadjacent each other, the metal being widestadjacent its ends and decreasin in width from said ends to form theresilient intermediate portion, a handle pivoted to one of said ends,and a cam-slot and pin connection between the handle and the other ofsaid ends.. 1

6. The combination of -'a; cap-embracing member shaped from a singleplece of metal with its ends adjacent each other, the metal belng widestad acent its ends and decreasing 1n width from said ends to form theresilient intermediate ortion, a ca enga in flange depending om saidembei handle pivoted to one'end of the member, and a cam slot and pinconnection between the handleand the other end of the member.

'7. The combination of a contractile capembracing .member' adapted toexpand for embracing a cap, means for setting the member in an ex andedand inoperative position, and means or contracting said member andcausing it to grip the cap.

In testimony whereof I afix my signature inv presence of two witnesses.
